6 Mojo::DynamicMethods - Fast dynamic method dispatch

9 package MyClass;
10 use Mojo::Base -base, -signatures;
11
12 use Mojo::DynamicMethods -dispatch;
13
14 sub BUILD_DYNAMIC ($class, $method, $dyn_methods) {
15 return sub {...};
16 }
17
18 sub add_helper ($self, $name, $cb) {
19 Mojo::DynamicMethods::register 'MyClass', $self, $name, $cb;
20 }
21
22 package main;
23
24 # Generate methods dynamically (and hide them from "$obj->can(...)")
25 my $obj = MyClass->new;
26 $obj->add_helper(foo => sub { warn 'Hello Helper!' });
27 $obj->foo;

30 Mojo::DynamicMethods provides dynamic method dispatch for per-object
31 helper methods without requiring use of "AUTOLOAD".
32
33 To opt your class into dynamic dispatch simply pass the "-dispatch"
34 flag.
35
36 use Mojo::DynamicMethods -dispatch;
37
38 And then implement a "BUILD_DYNAMIC" method in your class, making sure
39 that the key you use to lookup methods in $dyn_methods is the same
40 thing you pass as $ref to "register".
41
42 sub BUILD_DYNAMIC ($class, $method, $dyn_methods) {
43 return sub ($self, @args) {
44 my $dynamic = $dyn_methods->{$self}{$method};
45 return $self->$dynamic(@args) if $dynamic;
46 my $package = ref $self;
47 croak qq{Can't locate object method "$method" via package "$package"};
48 };
49 }
50
51 Note that this module will summon Cthulhu, use it at your own risk!
52
54 Mojo::DynamicMethods implements the following functions.
55
56 register
57 Mojo::DynamicMethods::register $class, $ref, $name, $cb;
58
59 Registers the method $name as eligible for dynamic dispatch for $class,
60 and sets $cb to be looked up for $name by reference $ref in a dynamic
61 method constructed by "BUILD_DYNAMIC".
